Lower motor was good. Upper motor was rust3d and seized. Removed upper motor and flushed with WD40 via small holes in the motor. Tapped on motor with a wrench and the motor shaft broke free. Flushed with more WD40 and turned motor till the crunching stopped and all rust was removed. 4wd works great now! Daved some $. Thank You for the video.

Just fixed mine! Thanks a lot!! Easiest way to clock it, is to match the rust marks on the shaft gears with the rust on the tooth of the gear from the actuator. I installed it using that method, added the larger cog as it will only fit the smaller cog one way. Rotated the gears as to loosen the shaft up. Mine was seized from lack of use, rotating the gears to pull that shaft back and forth while the truck was in neutral. So the small cog matched the rust spots, large cog on top, then install the cover last. Make sure to return the shaft to the 2wd position before all this. Also I disconnected the positive battery terminal to avoid lights on the dash, which worked. Also my motor was extremely rusted, can’t believe I freed it up. Didn’t solder the connections just reversed sides of the post so they are under tension when I reinstalled the motor. Works for now, will solder later. I did this process for both actuators, I have both 4 hi and lo now.

You can remove the actuator while leaving the two shift rods in the transfer case. If you remove both motors, the house will come out without the shift rods. The shift rods don't go bad so they don't need to be replaced. Saving your thousands in labor cost and time.

Maybe I need to cut hose now? I hear noises but doesn't engage. At least the 4Hi light doesn't flash in 2wd now

Like argy, where my vacuum hose slipped onto the nipple it was cracked and dry rotted, I “cut” a very small piece of the end off that was cracked and slipped the fresh cut hose onto the nipple. Now there was a perfect seal for the vacuum to activate the actuator. There is some extra slack in the hose but not much, cut off as little as possible to make sure it will still reach the nipple.

Thanks! This video and the comments, saved me $2500 as well. I did figure out a trick to get the spring tension to push in on the rod. Once you've timed the gear, offset it maybe 1/4-1/2 inch so that when the system repositions the gear to the default 2wd position it applies inward pressure on the rod.

Nick, I have the same problem. I don't know what the internal gear positions should be. I have a 2007 Tundra. My motor works... i took it out and tested independently. Put it back "together" but 4Hi is constantly blinking along with "VSC Off" indicator ON. I have a feeling the gears inside are not aligned... what was the setting when install the new one (assuming you turn on the truck in 2x vs 4Hi). The other thing i found out was that with the truck off, you can turn to 4Hi, then turn on the truck and it will engage but the side effect is that in order to get it back to 2x, you have to turn off the truck and switch the knob back to 2x and turn the truck on. Just found that out this weekend.

MrHastiin I had the same effect on my 07 Tundra. Here’s what I did: 1. Make sure key is off. 2. Connect actuator connectors but don’t install and make sure the actuator sensor is installed with everything in place except place the actuator tops (part with the motor and sensor) in a location where the sensor or gear isn’t going to fall out when actuated. There is a line to line up inside the actuator sensor with another part but that’s another story. 3. Turn your key on making sure your 4WD switch is in the “2WD” position. At that time the actuators will center themselves where they are supposed to be. 4.Turn key off and make sure both fork shaft gears are all the way forward (front of the truck). 5. Install actuator “hats” (parts with the electronics) cocked slightly to the front of the truck (you may have to move the gear position away from the 2WD resting position in order to properly mesh the drive gear with the fork shaft gear) and when meshed (only 1 tooth) rotate into position (this will allow proper spring tension holding the forks forward). 6. Final install the “hats” and connect the vent line (after making sure it’s not cracked). 7. Turn on key and you should hear the actuator load the spring tension. 8. Clear the codes even though it may not show errors (usually does). I use a wireless unit called “Foseal” with my iPhone 7plus with an app called “OBD Fusion” (yes, I paid for the app) and it allows me to clear the codes. 9. Turn key off and then back on and let the sensors work. You should be good to go or may have to remove and install a few times to get the mesh alignment and preload right (I did). My Hi/Low motor is too weak I think. I don’t have issues with my 4Hi anymore, only the 4Lo. The motor stalls out mid sensor almost every time.

Not sure, the difference in the hi, and low side is the upper motor has that vacuum line where it can rot and get water inside. the low side can only brake is for some reason the contacts on the motor come loose. Rust and water can’t really leak inside that unless the gasket was somehow damaged. Might be worth opening up just to check and see if that side is working.

OK, this has been a really good video, but I am having trouble with the reinstall. (2008 tundra) My truck got stuck in four wheel high and I took it apart, expecting the motor to be rusted or a terminal broken or the motor seized or something but seems to all function well. Tested all connections and everything looked good. We also hooked leads to the motor and ran it on 12 V and it was good as well. I got it into 2 Wheel Dr. by pushing the fork forward, but I still have the flashing lights on the dash and the four wheel high and low do not work. When I have the top section of the actuator off, but all the connectors plugged in, should the four wheel high function show me movement in park or neutral with the engine not running, but the accessory on? I have gotten it to “reset to 2 Wheel Dr.“ like another commentor suggested, but I am getting no movement when I switch to for high or for low. What gives? And what could have caused it to be stuck in the first place?

Will the car drive at all? And if it will are you able to have someone do a reset via the diagnostic port? Also are all the motor connection soldered strong. The occurrences where people climb under the car and hit it or it works sometimes and sometimes doesn’t means a bad electrical connection somewhere.

@@MSRWorkshop connections were good. Solder looked great, we even tested the connections with an ohm meter to make sure they were connected well. Should the actuator move when you put it into 4wd hi from 2wd - even if the 4 hi light is blinking on the cluster? Or do these codes have to be cleared before the actuator will try and operate? We can get the actuator to do the reset to 2wd when you first turn the key on but that’s it? I tried to get the codes cleared at an OReiley auto store and when the guy cleared them the still wouldn’t clear off the cluster after we restarted the truck 🤷🏼♂️

So I just put my truck into 4hi and 4lo today to move the fluids inside of the transfer case but I was in my driveway and I stopped and was currently in 4hi But then I put it in to 4lo And it's all of a sudden I am getting a check engine light and My whole dash screen lights are on such as 4hi, 4lo, traction control off on my multimedia display, can't even drive the truck, I put it in D, N, R, S1 to S6 and no luck, my truck is stuck and cannot move at all. So right now my truck is in the driveway as a lawn ornament and it's not able to move at all. So what could be the cause of this? So I have to borrow my dad's Camry the time being and I'm afraid I'm going to put down thousands of dollars to get this fixed. I'm scared that it's going to cost me lots of money and that's my only vehicle that I own and I do not want to put a lot of money to get this fixed but I wanted to get it moving again but I can't because of the idiot lights. I do have a $300 Inova scan tool And I did erase the codes but it just keeps coming back on again and so it repeated the process and it's just keep coming back on again so I don't know what's making my truck not to delete the DTC's, And yes I did also remove the negative and positive terminal on my battery but still no luck. It's telling me that it needs to replace the wheel sensors but I know that's not an issue because the truck drives fine It only happened and gave me this issue when I put it into 4lo. When I put it into 4hi It was fine but as soon as I put it into 4lo It screwed up my truck and now my truck is not drivable. Before all this happened I did took my truck for a test drive and it was working perfectly fine but now it's not. So what can be because of this exactly?

I tried this on my 2011, no luck, I’ve been dealing with this issue for 3yrs now. I finally had enough and paid Toyota to put a new actuator on which didn’t solve the problem, I also changed front/rear diff fluid, Tcase fluid (obviously with with the Actuator replacement) and the ADD actuator.. no luck. Still in the same boat. Dealership confirmed I have power going to both actuators. But it’s not engaging it 4hi or 4lo. (I also changed out the 4x4 control module under the glove box) and all fuses are good. The only think i haven’t changed the the 4hi/lo knob on the dash. But here I am with a 4x4 2011 tundra with no 4x4 function and it’s rather irritating. Any insight would help because I’m out of options. Ps: this happened right after the cam tower leak repair that I had done in 2019

Couple things. If you don't time the gear properly the spring tension might not be correct in both positions. You could end up with too much tension on one end and nothing on the other. Also, the electrical connections are microwelded, not soldered, as the soldered connections probably won't hold up to the vibrations.
@JH-tf2yn

@@MSRWorkshop yes they do fail. Just saying the factory doesn't solder them for a reason. Toyota and Aisin have a reason for everything. A person could fabricate a simple micro spot welder or buy one or just try the solder. Also if one was to attempt to solder the joints on the microswitch they will likely distort and ruin the switch. But the most important issue is the gear timing. The actuator puts spring pressure against the rod at the end of both positions. By guessing at the location you're taking a chance at overloading the motor, winding or other parts. And also possibly not getting any spring pressure at all which could cause the rod to move out of position during operation.

Very good information. My 2008 was in 2wd and wouldn’t go into 4H/L when I pulled the top (4wd) motor and the motor was just fine. I must not have it clocked right because now the 4H warning flashes all the time and doesn’t go into 2wd anymore. I should have run a diagnostic to identify the root cause before I did it. Does anyone know the clock position for the upper (4wd) motor? One picture would be worth a thousand words. Update: the still picture at the end of the video show the upper clock position is the point of the switch aligned to the #2 stamped on the rotating gear. I was successful in getting my 2wd back.
